JACOB KNAPP, OF CINCINNATI, OHIO.-

SHlFTlNG-RAIL FOR VEHICLES.

SPECIFICATION forming part of Letters Patent NO. 294,788, dated March11, 1884.

Application filed December 24, 1883. (No model.) i

which the following is a specification, reference being had therein tothe accompanying drawings.

My invention comprises a special form of clip-nut that enables theback-braces, armrests, and rail of any kind of a vehicle to be readilycoupled to the seat-irons and to be as readily detached from these ironswhen occa- Said device consists of a,

hub or nut proper, which is adapted to be traversed with the back-bracesand front ends of the arm-rests, the nut having a hook-shaped clip that.engages over or under the rail, to which latter the buggy-top is appliedin the usual manner. The clips being hooked over this rail and theproper ends of the back-braces and arm-rests being passed through thehubs, and also through suitable holes in the seatirons, ordinary nutsare then screwed onto said braces and rests, thereby clamping said rail,braces, and rests immovably to said irons, as hereinafter more fullydescribed.

In the annexed drawings, Figure l is a perspective View of a buggy-seatprovided with my improved attachments. Fig. 2 isan enlarged verticalsection through one of my clipnuts and its accessories. Figs. 3 and 4are similar sections of two modifications of the invention.

Referring to Fig. 2, Arepresents the hub of the nut, which hub may be ofany ornamental shape, and is here represented as being screwthreadedinternally at B, to admit the male threads cut on the proper ends of thebackbraces and arm-rests. Projecting from this hub or 'nut is ahook-shaped Y clip, 0, adapted to engage snugly over an ordinary rail,D, which has the customary front bearings, E E, and back-props F F, forsupporting the buggy-top in the usual manner. Secured to thevehicle-seat G are the irons H, pierced near their outer ends, as shownat I in Figs. 2, 3, and 4:.

J J are customary braces that assist in supporting the back K, the lowerends of said braces having threads jj out upon them.

L L are arm-rests attached at rear to the back K, and having their frontends threaded at Z Z.

N are customary nuts that engage with the screws j j Z l and bolts 0 O,the latter being fastened in the seat-irons located near the back props,F F.

' After the perforated irons H I have been properly fastened to the seatG, the rail D is placed in position on said irons, and the clipnuts Aare engaged with the threaded ends jj and Z Z of the back-braces andarm-rests, care being taken to have the hooks G of said nuts presentedtoward said rail. These threaded ends of the braces and rests being nowpassed through the perforations I of irons H and the nuts N screwed uponsaid threaded endsjj U, the rail D is not only immovably clamped to saidirons, but at the same time the back K is fastened to the seat G.Finally, the short bolts or screws 0 O are then engaged with the rearirons atthe opposite sides of the seat, for the purpose of stiffeningthe rail in the immediate neighborhood of the back-propsF F. This actcompletes the application of my attaohments and affords a structure thatis practically as durable and secure as though the rail, backbraces, andarm-rests were welded to the seatirons, and yet the construction is suchas to allow the ready removal of the buggy-top at any time. This removalis effected by simply disengaging the various nuts N and removing theback K, with its braces J J L L, so as to allow the railD and itsattached top to be at once .lifted off the seat, to which latter saidback can be again applied in a few minutes.

Reference to Fig. 2 shows that the hook or clip 0 is made sufficientlyshort to avoid coming in contact with the seat-iron H when the hub A Bis screwed firmly against said iron. This arrangement secures the mostrigid clampingof the railD in its proper place; but to prevent thepossibility of a person s garments being caught under the end of saidhook, the latter may be extended so as to enter a groove or pit, h, inthe upper surface of the seat-iron, as seen in Fig. 3. Furthermore, thisillustration shows that the hub Ahas a smooth bore, 1?, to to admit theunthreaded brace J, the latter inwardly-projecting hooks C, that graspthe rail 1), said nuts being traversed bythelower ends of back-braces JJ and arm-rests L L, which braces and rests are retained in place byscrewing upon them the customary nuts N, as herein described.

In testimony whereof I alfix my signature in I presence of twowitnesses.

having a collar, R, swaged on it which collar rests upon said hub. InFig. l the seat-iron H has an upward bend, S, to receive the top of railD, the clip-nut A 0 being in this case applied beneath said rail, whereit will not be so conspicuous. It will thus be seen that said nut can beapplied in any manner that will be most effective in clamping the railto the seat- 11011S.

I claim as my invention In combination with the ordinary seat-irons H,perforated at I, the nuts A, provided with \Vitnesses:
